[Details]
• If the values of m is out of the specified range, nL and data following are processed as normal
data.
• The nL and nH indicate the number of dots of the bit image in the horizontal direction. The
number of dots is calculated by
nL + nH × 256.
• If the bit-image data input exceeds the number of dots to be printed on a line, the excess data
is ignored.
• d indicates the bit-image data. Set a corresponding bit to 1 to print a dot or to 0 to not print a
dot.
• If the width of the printing area set by GS L and GS W less than the width required by the
data sent with the
ESC ∗
∗∗
∗ command, the following will be performed on the line in question
(but the printing cannot exceed the maximum printable area):
① The width of the printing area is extended to the right to accommodate the amount of
data.
② If step ① does not provide sufficient width for the data, the left margin is reduced to
accommodate the data.
